Figure 4From: Characterization of the decline and recovery of heat-treated Scenedesmus vacuolatusThe MTT assays for the succinate dehydrogenase activity of Scenedesmus mitochondria. The relative activities of heat-treated (○) and untreated (●) cell cultures are plotted as functions of the time of dark cultivation. All the data are normalized with respect to that of untreated cells at the beginning of dark cultivation. Each data point represents the mean ±SD of three independent measurements with two replicates each.Back to article page
